// Script to delete old notifications and send notification emails.
// Run once a day.

// We send emails for notifications generated in the last day.
// This is a slight kludge - since the timing of period tasks
// is not precise, notifications may be delivered twice or not at all.
// We use a 1-hour slop factor to err on the side of twice.
